Introduction
Hunt the Wumpus is a game set inside the cave of the Wumpus, a scary, gold-hoarding monster who
likes to eat people who disturb its sleep. The player’s goal is to guide an adventurer to kill the
Wumpus, find its hidden gold, and escape alive. The Wumpus lives in a large cave of rooms
arranged in a grid, where each room has four tunnels leading to the rooms to the north, east, south,
and west.
The adventurer starts the game in a random empty room in the Wumpus’ cave. Her starting position
is also the location of the escape rope that she must use to escape after she’s completed her task.
Each room may be empty, or it may contain one (and only one) of four “events” (all described below):
two kinds of dangerous hazards, the terrifying Wumpus, and the gold treasure. When the adventurer
is in a room that’s adjacent to one containing an “event”, the player will receive a percept (a
message) to inform them about the event the adventurer is close to.
If the adventurer perishes while searching for the Wumpus, the player should be presented with the
option to start the game over with the same cave configuration, start the game over with a new
random cave configuration, or quit the game entirely.
The player wins the game if they can safely guide the adventurer through the cave to kill the
Wumpus, pick up the gold, and make it back to the escape rope unharmed!
Note: If you enter the cave, retrieve the gold, and escape without killing the Wumpus, that’s okay too.
The player still wins.
Game elements
The adventurer
Each turn you may take one of two actions to guide the adventurer:
Move: You can move through a tunnel to an adjacent room.
Fire an Arrow: The adventurer begins the game with three arrows. As long as the adventurer still
has at least one arrow, the player can choose to fire one in any direction (i.e. north, south, east, or
west). The arrow continues flying in the same direction until it hits a wall or travels through three
rooms. If the arrow enters the Wumpus’ room, it pierces the Wumpus’ heart and kills the
monster. As noted above, if you want to design the game such that the player can win by safely
retrieving the gold (and not killing the Wumpus), that’s okay too.
The Wumpus
Usually, the Wumpus is peacefully asleep in its cave. Two things wake the Wumpus up, however: the
adventurer entering its room or shooting an arrow and missing it. If the Wumpus wakes up while in
the same room as the adventurer, the Wumpus will angrily eat the adventurer, ending the game. If
the Wumpus just wakes up from hearing an arrow being fired, though, there’s a 75% chance it will
move to a random empty room in the cave to avoid being found.
Hazards
There are two kinds of hazards in the Wumpus’ cave:
Bottomless pits: Two of the cave’s rooms have bottomless pits in them. If the adventurer enters
a room with a bottomless pit, she falls in and dies, and the player loses.
Super bats: Two rooms have super bats. If the adventurer enters a room that contains super
bats, an angry bat grabs her and takes her to some other room at random (which could be
dangerous!).
The gold
The gold is a treasure sitting in a room that contains neither a hazard nor the Wumpus. If the
adventurer is in a room containing the gold, she automatically picks it up and takes it with her.
Percepts
When the adventurer is in a room directly adjacent to to a room containing an “event”, the player
receives the following messages:
Wumpus: “You smell a terrible stench.”
Super bats: “You hear wings flapping.”
Bottomless pit: “You feel a breeze.”
Gold: “You see a glimmer nearby.”
Notice that there’s no percept for the escape rope! That means the player will have to remember
where they started and find their way back to that tile after they’ve completed their task.

As an example of how the percepts work, if the adventurer is standing in an empty room with the
Wumpus one room to the North, the Gold one room to the East, and Bats two rooms to the South,
they would receive the following messages at the beginning of their turn:
You smell a terrible stench.
You see a glimmer nearby.
Remember, the percepts don’t tell you where the hazard or gold is, just that it’s somewhere close!
Program requirements
Your program should allow the user to play Hunt the Wumpus, as described above.
The Wumpus’ cave is represented by a square grid. The size of the grid (i.e. the number of rooms
on one side of the square) should be specified as a command line parameter to your program.
Caves smaller than four rooms on a side aren’t allowed. You should visualize the grid to allow the
user to play the game. In particular, you should display the grid, and indicate within the grid which
room the player is in. An example visualization of a 4×4 grid might look like this, where
the * character represents the location of the adventurer:
+—+—+—+—+
| | | | |
| | | | |
| | | | |
+—+—+—+—+
| | | | |
| | | | |
| | | | |
+—+—+—+—+
| | | | |
| | | * | |
| | | | |
+—+—+—+—+
| | | | |
| | | | |
| | | | |
+—+—+—+—+
Your program must also accept a second command line parameter which will be either “true”
or “false”. If the parameter is set to false (e.g. ./wumpus 4 false) then the program will run as
normal. If the second command line value is specified as “true” then your game must operate in
debug mode.
When your program in operating in debug mode, the player’s map will show a “cheat view” with
locations marked for each of the following: wumpus, bats, bottomless pits, gold, player, escape
rope.
To navigate the cave system, the player must be able to type “w” (north), “a” (west), “s” (south), or
“d” (east). In order to fire an arrow, a space (” “) should be used, followed by either “w”, “a”, “s”, or
“d” to indicate the direction. For example, the user would enter ” d” to fire an arrow towards the
east.
2020/2/23 Program 4
https://oregonstate.instructure.com/courses/1758070/assignments/7800083 4/7
Your code must have the following classes: Room , Event , Wumpus , Bats , Pit , and Gold . You may
create more classes if they would be helpful.
The Event class must be abstract , and the Wumpus , Bats , Pit , and Gold classes should all be
derived from Event . Remember, any event does something when the adventurer enters the same
room as the event, and will display a message when the adventurer is nearby. Your design of
the Event class should reflect this. For example, your Event class might have
a percept() method that is called whenever the adventurer is in a room adjacent to the event,
where the Wumpus , Bats , Pit , and Gold classes implement their own specific versions of
the percept() method. Similarly, your Event class might have an encounter() method that is
called when the adventurer enters the same room as the event, with the individual event classes
implementing their own specific versions of encounter() .
You must use the Event classes polymorphically. In other words, your Room class may only
contain a member of the Event class but not members of the Wumpus , Bats , Pit ,
or Gold classes.
Each Room contains at most one Event , but it’s possible that it contains no Event . The design of
your Room class should reflect this.
The grid representing your cave should be implemented using the std::vector class.
Your program may not have any memory leaks. I strongly recommend that you use Valgrind to
occasionally test your program as you develop it (even when everything seems to be working).
The Big 3 must be implemented as appropriate.
Your program must be factored into interface, implementation, and application. Specifically, you
should have one header file and one implementation file for each class, and you should have a
single application file containing your main() function. You should also include a Makefile that
specifies compilation for your program.
Lack of correct coding style will incur an automatic 6 point deduction. You must follow the spirit of
the assignment.
Hints
Polymorphism only works when you are working with references or pointers. If you use the value
of an object directly, it may not select the correct member function.
Hunt the Wumpus is a game all about hiding information from the player, which might make it
hard to debug! Your life will be easier if you implement the debugging mode first and then finish
your implementation of the final version
Extra Credit
In addition to the requirements above, you may earn extra credit as follows:
(6 points) Implement an AI class that plays the game for you. This AI class should use the same
interface to the game that the player does. That is, it should use percepts to learn about the world
and make decisions.
(4 points) Implement the WASD controls so that the user can simply press the desired key (to
move locations) without needing to press “Enter” afterwards.

Implementation Details
As with the previous program, you have additional freedom to design your own implementation.
There are certain baseline requirements as specified in this document. However, the exact member
functions and member variables are up to you.
Be sure to design your program on paper. Use scratch paper with flow charts or pseudo-code. In
particular, think of how your program will flow. What will the constructors do? How will you pass
objects and variables between different classes? Taking the time to do a thorough program design
can save you hours of frustrating debugging time!
On the topic of debuggers, I strongly recommend that you choose a debugger and get familiar with its
operation (GDB, Visual Studio, etc). As your programs get more complex it becomes even more
useful to instantly know the value of all your variables and memory contents.
Programming Style/Comments
In your implementation, make sure that you include a file header for every .cpp or .h file. Also ensure
that you use proper indentation/spacing and include comments! Below is an example header to
include. Be sure to review the style guidelines for this class
